摘要：

We discuss the relations between the metallicity gradients and the other characteristics of a set of dwarf elliptical galaxies in different environments dagger. We suggest that dEs have typically metallicity gradients of -0.30 +/- 0.25 dex/r(e), unrelated to their mass. Dwarf elliptical galaxies with embedded disks, or dS0, may have flat metallicity gradients.
